What is the difference between a visitor's permit and a visa?

According to the

The Consulate General of the Republic of Serbia in Shanghai >>

Travel to Serbia,

Holders of Taiwanese passports are issued visitor’s permit for entry into the Republic of Serbia.

I'm confused about the difference between a visitor's permit and a visa.

What is the difference between them?

Does a visitor's permit mean that Taiwanese citizens

don't need to apply for a visa,

but will be issued a visitor's permit on arrival in Serbia?
